Info

@Normmatt has created a way to run B9S .firm files from bootrom via a DSi Flashcard and a magnet! This works on every 3DS on any firmware version.

For installation without a PC, user @TheCyberQuake has created a pack which will automatically install B9S and copy over essential starter homebrew from the flashcard's SD to the 3DS's. This will mainly be used for PC-less B9S installations. If you have a PC with you, use 3ds.guide. Read more here: https://gbatemp.net/threads/481141/

How does this work?

This works because of a flaw in the bootrom. Before the bootrom boots the NAND, it checks to see if Start+Select+X is held down, and if the shell is closed. If these requirements are met, it will boot an NDS cartridge from the bootrom. This give that cartridge bootrom access. You might be wondering how you'd hold down buttons while the shell is closed, and why you need a magnet. If you put a magnet in a specific spot on the 3DS, it will go into sleep mode. Using this, you can boot the NDS cartridge with the buttons held down while in sleep mode! Using a reflashable flashcard, you can boot B9SInstaller using the flashcard, and easily install it on your 3DS.

The 2DS doesn't need a magnet since a switch puts it to sleep instead of a magnet.

What does this mean?

1. Any 3DS model on any firmware can be hacked with minimal effort
2. You can unbrick any 3DS model from any type of brick.
   - Remember, you don't need a NAND backup for this. Just do a CTRTransfer.
   - This does not apply to MCU bricks.
3. Even consoles with fried NAND, or even the NAND chip physically removed, can use this

This is incredibly impressive stuff, and will most likely be released soon! edit: now!

FAQ

Q: Can Nintendo patch this?
A: Nope! Not without a new hardware revision.

Q: My flashcard is blocked by my firmware! Can I still use this?
A: Yes! The flashcard blacklist is not enabled on the bootrom.

Q: Why can't this work with my flashcard?
A: The installation requires you to flash NTRBoot to the flashcard's nand. Most DS flashcards, such as the original R4, have a ROM, which is not flashable.

Q: Can I install NTRBoot on my flashcard without another 3DS system?
A: If you can run NDS roms on your 3DS with it, then yes. If it's blocked on your 3DS version, then you'll need another 3DS system to use it.

Q: Will my 3DS flashcard work?
A: No, only the NDSi flashcards listed above.

Q: Will any other flash cards work?
A: Only the ones listed in the OP. However keep in mind that flashcards such as the DSTT, Supercard DS2 and R4 SDHC Dualcore are planned to be supported in the future.

Q: I tried to do this with my cartridge and it didn't work?
A: It doesn't work with regular DS cards.

Q: Can I unbrick from a ____ brick?
A: Considering the card has access to the bootrom, yes! This can unbrick any brick (except MCU), unless you've taken a knife to the motherboard.

Q: Can I install B9S on the latest firmware with this?
A: Again, since the card has access to the bootrom, you can do this easily! Just plug in your flashcard, boot up using the magnet and button combination, and install.

Q: Does this work on the New Nintendo 2DS XL?
A: Yes!

By reprints do you mean clones? I bought a card from there the other day and it's not delivered yet. If it is a clone, will it work as well as the original?

They're 1:1 clones of the originals as far as I know. AKAIO sees it as an original so there shouldn't be any problems.

I would like to mention that all Ak2i carts on the market are 1:1 clones. I compared them to my real Ak2i that I got many eons ago and the hardware is virtually the same. In fact this entire thread that I made here, is using that 1:1 clone. So even the official updaters provided by the Acekard team detect this cart as an "official cart." The Acekard team most likely sold their board, design, etc. when they disbanded and thus we are getting 100% perfect clones. So not only is possible for new ones to be reprinted, they are already reprinting new ones.

I also own one of the nds-card.com clones and can verify it is a 1:1 clone. Which at that point can it even really be called a clone?

It's sort of like the ship of Theseus

I'd call it a repro tbh

It's not an official cart, but it is using official hardware. So it's a literal clone.

I guess it falls under literal definition, but typically a clone in the gaming world would use unofficial hardware to imitate the real thing.

It's witchcraft, obviously.

will a DSTT be suffice as of right now? or do I need to wait longer for support after it this hax hits?

The DSTT has a ROM, not a NAND. This means that the firmware could only be flashed once and that's it. This limitation applies to all ROM based flashcarts. This patch will most likely only work DSi flashcarts as they actually have a NAND to write to.

Time to buy an iEvo too then before they become £150 each

 

[Ramses]

god it. i'll keep this in mind then, i'll see what I can do for another cart, or i'll just flat out replace the Mobo on my bricked one and start a new

 

[froggestspirit]

curious if my r4i gold will work, or m3i zero (I know the m3i zero had some firmware updating sort of thing with a weird cable)

You don't get an answer to that because nobody knows.
Seriously people stop asking "will x flashcart be supported" because nobody knows except a few that don't give info until release.

 

[Beerus]

You could say that im "attracted" to this hax

ill leave now

Chances are that they are going to aim for easy carts to buy and flash. M3i zero was an extremely difficult cart to work with and the the M3 team went out of their way to make it that way

 

[Deleted member 350372]

Not asking if this will work with these flashcarts, but hopefully they will in the future.

I have:

1. R4i SDHC 3DS RTS

2. R4i Gold

I used these a long time ago to hack MKDS via ROM & cheat codes.

 

[Spore2]

I don't appreciate stuff when they are teased months before being released. Then in some cases they are never released.

 

[Shad0w136]

Yea, ill be honest. I get pretty annoyed waiting and checking the forums everyday for this post and the other like it, only to find out that there is no actual information about its release or development.

 

[Deleted member 381889]

I'll update the OP if any more news is released
